I'm afraid you have no argument there, there's no rational basis to suggest either Cilic or Raonic are overranked at the moment. It might be true that a good share of their ranking points comes from smaller events, but it's not like the guys ranked below them - or rather in the same area of the rankings - are getting any better results in the big events - well on the contrary.

No,I'm not suggesting they are overranked.But they both lack big results in big tournaments,especially Cilic.
So,everyone is a vulture one way or another I like vultures.

Milos generally starts slow in tournaments (IMHO it is getting feel for surface in match conditions rather than a lack of focus against lower ranked players that is his problem) ... so since this is his first match because of the WO, AD to Cilic. But if Milos finds his game, and is playing anywhere near what he did in SJ vs Hass / Querry, I think he wins.

Depends which Cilic will show. If Marin will play good he will win because he like big servers. He has good return plus he is better baseliner and his serve is too good for average returners.
Problem is he lost badly to Nishikori and that could be a problem. He thought he will jump into top 10 but he false and self-confidence is low now (it was obvious how happy he was beating just Ramos).
